To 'all whom t may concern.'

Be it known that I, Lnwis Dennis, a citizen of the United States, residing at Nashville, Davidson County,` Tennessee, have invented a new and useful Gasoline Fil-ling Nozzle, of which the following is a specification;

This invention relates to gasoline filling nozzles c The usual equipment employed by gasoline lilling stations, etc., for filling the gasoline tanks of motor vehicles with gasoline comprises a relatively heavy hose of considerable llength connected at one end with the pump or supply mechanism from which the gasoline is taken,- and provided at its opposite end with a metallic nozzle adapted to be extended into the inlet opening of the gasoline tank on the motor vehicleso that the gasoline taken freni the source of supply will be discharged inte the gasoline tank of the motor vehicle. Due to the weight of the relatively long and' heavy hose leading frein the` source of supply to the gasoline tank of the motor vehicle it' frequently occurs that when the weight of the hose is increased by the gasoline passing through it, the nozzle is drawn ont of the inlet opening of the gasoline tank and the gasoline flows from the hose to the ground and is wasted'.`

An object of the present invention is to provide a novel and efficient device for holding the nozzle in the inlet opening of the gasfiline tank of the motor vehicle so that when the weight of the connected hose is increased by the gasoline passing through it the' nozzle cannot become detached or drawn out of the inlet opening.

Other objects will appear from the following description, reference being made to the drawing in which- Fig. l is a longitudinal sectional view vof my present invention in connection with the inlet of a gasoline tank.

Fig. 2- is a cross sectional view on the line 2 2- o't Fig. l. y

Fig. 3 is a sectional view on the line 3-8 of Fig. l.

My improved filling nozzle is designed and adapted for use in connection with the usual filling hose l for conducting the gasoline from the source of supply to the nozzle and thence intothe gasoline tank of a inotor vehicle, or the like- As shown, my irnproved nozzle comprises a tubular portion Q. having teleseoping or other connection with the hose l and, in the present instance, beingteles'coped within the end of the hose l and having a circumferential flange 8 serving 'las an abutment for the end of the hose. The telescoping connection on the two parts forms a leak-proof joint.

The end of the nozzle 2 is provided with a pair of projections l which may be two rounded corners of a triangle as will be understood by reference to Fig. 3, and which are freely insertable in and withdrawable from the inlet opening of gasoline tanks on motor vehicles;

p A lever 5 hasone end pivoted tothe nozzle 2 and the free end terminating in line with `or approximately in line with the end of 'the nozzle 2. las shown, the lever 5 extends between a pair of ears 6 rigid with the nozzle 2 andli's mounted upon a pivot 7 supported by said ears. y A spring barrel 8 in connection with the lever 5 extends in a direction away from the nozzle 2 and encloses a spring 9, the outer end of which abuts against the end of the spring Varrel and the inner end of which presses a slidable element l0 into contact with the nozzle 2. The spring 9 is of the expansion type and its power is exerted to actuate the free end of the lever 5 in a direction away from the nozzle 2, with the result that when the ends of the nozzle and the lever are placed within the inlet opening of a gasoline tank, said nozzle and lever are spread apart and held into contact with the walls of the inlet opening forming a gripping device that will hold the nozzle in position even under the `increased weight of the gasoline llowing through the hose. Thus waste of gasoline is prevented.

The lever 5 is formed with a loop or ring l1 embracing the nozzle 2 and having a handle or hand lever l2 in connection therewith on the side of the nozzle 2 diametrically opposite from the lever 5; The ring or loop ll is of sufficient size to permit manipula tion of the handle 12 to move the lever 5 toward the nozzle 2 and toipermit the spring 9` to actuate the lever 5 somedistance away from the nozzle. Extent of ino-vement of the lever 5 away from the nozzle 2 is limited by contact of the ring 11 with the nozzle so that the part 1Q cannot become detached.

The end of the lever 5 has an enlargement 13 thereon corresponding to the proflowing through the hose 1.

jections 4 and forming the third corner or apex of the triangle. The enlargement 13 is adapted to form gripping engagement with the inner surface of the inlet opening in the gasoline tank under pressure of the spring 9, while the projections 4 also engage the inner surface of the inlet opening.

'From the foregoing it Will be seen thatl when it is desired to insert the nozzle in the inlet opening of the gasoline tank it is only necessary to engage the nozzle 12 and press it tovvard the nozzle 2, thereby moving the free end of the lever 5 close to the nozzle to permit the end of the nozzle and the lever 5 to be inserted in the inlet opening. Then the handle l2 is released the spring 9 presses the nozzle and the lever 5 apart causing the projections 4 on the nozzle and the enlargement 13 on the lever to form gripping engagement with the inside of the inlet opening. The spring 9 is strong enough to cause the vparts to obtain gripping engagement that Will prevent the nozzle from dropping or being drawn out of the inlet opening even under the increased Weight of the gasoline Thus possibility of loss or Waste of gasoline, that Would occur should the nozzle become detached from the gasoline tank, is Wholly prevented and all of the gasoline is saved. When it is desired to remove the nozzle it is only necessary to release the gripping engagement of the parts 4 and 13 With the inner surface of the inlet opening by proper manipula'- tion of the handle 12.

From the foregoing it Will be seen that my invention is a very simple and highly etlicient device for obtaining all of its intended objects and purposes. The device may be economically manufactured and installed and effects a real and substantial saving by preventing the loss of gasoline due to the accidental disengagement of the nozzle from thegasoline tank.

I am aware that the construction and arrangement may be varied from that shown and I do not restrict myself to the exact form shown and described, nor otherwise except as Within the scope of the appended claims.

W'hat I claim and desire to secure by Letters Patent is 1.
